Translation from Group in Menschliche Gruppe is misleading and not CIDOC comform, because a group can also contain legal body.

Update:

This isn't a translation issue (see notes) but we should look into the situation nevertheless because at the moment it is possible to add groups or legal bodies to other groups/legal bodies. Question is if it should be possible.

We leave the decision about the membership of groups in legal bodies and vice versa to the user. Both would be CIDOC CRM conform and there might be cases in which this can be needed, even if we now cannot think about such a case. Thank you for reporting anyway.
